How to get the Download URI if I have the Storage Location

Question

I created an app and when I upload an Image I'm storing in a database the "Storage Location" of the file

Storage location gs://******/carriersPictures/calinonaca1@gmail.com-profilePicture-1570123057815.jpg

for example, I store this because I didn't find a function to store the download URI only the Storage Location of file using this

 picturesUrls.add(taskSnapshot.getUploadSessionUri().toString());

But, I want to display those images in a web page. I'm using NodeJs as backend with template view EJS. But how can I convert in the NodeJs app the Storage Location URI to download URI.

exports.getApprove = (req,res,next) => {
const email = req.params.email;
const ref = firebase.database().ref("User");
ref.orderByChild("email").equalTo(email).on("child_added", function(snapshot) {
    let pictureUrls = [];


    for(let i = 0 ;i < snapshot.val().picturesUrls.length ;i++) {


        pictureUrls.push(snapshot.val().picturesUrls[i]);
    }


const user = {
    CVC: snapshot.val().CVC,
    activated: snapshot.val().activated,
    address: snapshot.val().address,
    cardnumber: snapshot.val().cardnumber,
    city: snapshot.val().city,
    cnp:snapshot.val().cnp,
    country:snapshot.val().country,
    email:snapshot.val().email,
    expiredate:snapshot.val().expiredate,
    fullname:snapshot.val().fullname,
    password:snapshot.val().password,
    phone:snapshot.val().phone,
    pictureUrls: pictureUrls,
    rate: snapshot.val().rate,
    state: snapshot.val().state,
    type: snapshot.val().type,
    zipcode :snapshot.val().zipcode

}

res.render('main/approve', {
    pageTitle:'Drivie | APPROVE',
    path:'/aprove',
    user:user

  });


});
}

I want picturesUrls array to get the Download URLs not the Storage Location. I mean, I know in my database I store the Storage Locations of the images, but how can I query the storage for every Storage Location URL to get the Download URL. Didn't find too much in the official docs.

Thank you very much!

The download URL can only be retrieve from the client-side Firebase SDKs for Cloud Storage. The closest equivalent in the server-side SDKs is a signed URL, which is shown here: https://stackoverflow.com/questions/42956250/get-download-url-from-file-uploaded-with-cloud-functions-for-firebase — Frank van Puffelen, Oct 03 '19 at 18:33
